The traces took place in the immediate vicinity of the town of Stockton, Minnesota. Additional dye traces have been completed within an approximate ten mile buffer of this area. They include traces on the South Branch of the Whitewater River, Rush Creek, Crystal Springs State Fish Hatchery, and Ahrensfeld Creek. The majority of the previous traces were conducted to develop springshed mapping in support of trout stream management. The Stockton areas traces were conducted to further delineate springsheds in the area, characterize sinking streams in the Cambrian St. Lawrence Formation, and characterize surface water‐groundwater interactions in the county. Characterizing sinking streams and their connection to cold water springs is important as numerous trout streams are located in southeastern Minnesota.enDye TracingDye TraceKarstSpringsSinkholeFluorescentDyeSpringshedSinking StreamPseudokarstReport
